On: Unit tests fail when run in Australia

[Someone]

If it takes several seconds to set up a test, I would give this a try:

  - start a test from the IDE,
  - wait a second or so,
  - manually pause all threads,
  - look at the stacks of the threads.

Might take two or three attempts, but likely should learn you a lot. Alternatively, use a real profiler to find the call(s) that take lots of time.
